There are two ways to learn the correct tyre size:
Choosing a suitable tyre size for your car with a few parameters
1. The easiest and most reliable way is to check the size of the tyres you have used before. The picture shows how this information is provided.

2. Alternative variants of the tyre sizes can be found in the service and repair manual for your car. Furthermore, this information is specified on the pillar, on the front door end at the driver's side, on the fuel tank cap and on the glove box lid. But the best way is to check the size on the old tyres.

20 inch tyres for SUVs and crossovers are usually installed on powerful premium vehicles. In standard car configuration, they are used on Toyota Tundra, Porsche Cayenne, Land Rover Discovery, Chevrolet Silverado, Mercedes-Benz AMG GLE and others.
Features of 20 inch tyres for SUVs and crossovers
20 inch tyres are often installed by car owners instead of standard tyres in order to improve certain characteristics of the vehicle. For example, low-profile tyres with rim diameter equal to 20 inches ensure better steerability of the vehicle, as compared to high profile 19-inch tyres. At the same time, full-profile 20 inch tyres are much more comfortable than 21 inch original tyres.
Benefits of installing 20-inch tyres with profile height less than 55%:
Excellent steerability and maneuverability. Due to the low profile and reinforced carcass, they ensure good vehicle steerability, excellent roadholding ability and precise reaction to steering commands. However, one should keep in mind that when too wide tyres with high resistance to lateral skid are used, the force required to rotate the steering wheel may increase.
Good traction and grip. The increased contact patch helps to improve grip, and to reduce the braking distance on dry pavement. However, the risk of aquaplaning increases significantly in the rain.
High speed index. Low-profile tyres are made of a special rubber mix, with the properties best manifesting themselves at high speed after sufficient warm-up. They are only to be used on high quality asphalt roads, since moving over bumps significantly increases the risk of damaging the elements of suspension.
The benefits of installing 20 inch tyres with profile height over 55%:
Resistance to mechanical damage. High profile tyres for crossovers and SUVs have sturdy sidewalls and a reinforced carcass, and are resistant to punctures and cuts.
High level of comfort. The optimum height of the profile and excellent damping properties of the sidewalls contribute to efficient absorption of bumps caused by off-road driving or driving on poor quality roads. Not only it increases the level of the driver and passengers' comfort, but also prevents the risk of damaging the running gear elements.
It also makes it possible to increase the ground clearance. By installing higher profile tyres, many car owners try to increase the clearance, which is particularly important if the vehicle is operated on rough terrain and in heavy off-road conditions. However, such tuning requires careful calculations, expanding wheel arches, replacing certain suspension components and increasing the engine power; therefore, it is only possible in specialized workshops.
Popular standard sizes of 20 inch tyres for SUVs and crossovers are the following:
275/55 R20. This standard size is typical of tyres like Hercules Terra Trac A/T 2, Cooper Discoverer CTS, and Falken Ziex S/TZ 01.
